decompile an app binary to get back to source code

Question

Is there anyway to take a binary - even signed by yourself, and get back to the code? I\'m trying to recover something that I deleted a while ago... but have the binary here

Answer 1

You might want to have a look at Hex-Rays decompiler. You need to have IDA Pro debugger to use it.

Answer 2

You can disassemble a binary and get back assembly source, but there is no way to get back your original Objective-C structured source code.

EDIT: You may want to give Hopper a try. I didn't try it personally yet but Mike Ash says it's good.
